The post Circle Expands USDC Use to AI Agent Payments With x402 Integration appeared on BitcoinEthereumNews.com.
TLDR: Circle integrates USDC with x402 to enable automated machine-to-machine payments at scale. Gateway batching feature cuts gas costs for high-frequency micropayments across chains. Circle works with Google on A2A and AP2 protocols for agentic crypto transactions. Developers can explore AI agents paying in USDC for data, compute, and content. Circle is moving to expand how AI systems transact online. The company announced efforts to link its USDC stablecoin to x402, a protocol designed for agentic transactions. The integration targets machine-to-machine micropayments that operate at scale. Circle also joins Google’s A2A and AP2 initiatives to test autonomous payments. These moves aim to enable AI agents to pay for services, data, or compute in real time. According to a tweet from Circle, their approach focuses on programmable, interoperable, and fast payments for AI agents. They encourage developers and researchers to review the x402 GitHub proposal and contribute. The initiative represents a broader push to create financial infrastructure suitable for high-speed, low-friction machine transactions. AI is transforming how software interacts with the world, and payments will be no exception. At Circle, we believe @USDC is uniquely suited for machine-to-machine micropayments. It is programmable, interoperable, and near-instantly usable across the open internet.

By integrating with x402, it can handle thousands of transactions simultaneously. The new batching feature, soon on testnet, bundles transactions offchain to reduce gas costs. This allows micropayments to settle efficiently onchain, preserving finality while lowering costs. The integration also supports cross-chain transactions. A buyer on one blockchain can pay a seller on another, using a single USDC balance. This creates a more flexible, interoperable environment for autonomous agents. Circle highlighted these features in a detailed x402…
